In a recent interview with Gamespot, John Koller talked much about the recently unveiled PSP-3000: the improved screen, microphone, bundled releases, and more. In that interview, he revealed that the battery life of the new PSP model will indeed be decreased by about 20 to 30 minutes.
Koller explains that this is because of "a larger power draw with the brighter screen." Aha, just as I expected. Well, "20 to 30 minutes" of a shorter battery life isn't that much of a drawback, methinks. And for those who think that it's the end of the world because of the decreased battery life, Koller confirms that there's still going to be other options out there:
That's going to be off-set because we're still going to have the extended life battery that's still available for the consumers, so they're still going to get the 8 to 10 hours out of that battery. Or the battery that comes with the PSP will now be right around three and a half to four hours.
As for other components, the PSP-3000 model will have the same compatibility with the Slim accessories - they want everything out in the market to work with the PSP-3000.
It's also been confirmed that the Slim will be phased out eventually. Koller says production of the PSP-2000 will cease by September. Already?! If you're a collector of sorts, better make sure you grab a Slim unit ASAP!
